Xenon discharge headlamp.
This is one of those really annoying dazzling headlights you see on cars more expensive than yours. Unlike many you find on eBay it is an actual xenon arc discharge lamp, not a common xenon gas-filled incandescent bulb that many sellers misrepresent as being of this much more expensive type.Source:eBay seller tjauto04Contributor:Theodore GrayAcquired:11 March, 2009Text Updated:12 March, 2009Price: $25Size: 3"Purity: <10%
